Embodiment Construction

[0013] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0014] Usually, when the calling function calls the called function, it is assumed that the called function will modify the values ​​stored in all registers in the CPU (central processing unit, central processing unit). On the call stack, and after the function call ends, the value saved in the call stack is restored to the regist...

Abstract

The embodiment of the invention provides a program code compiling method and device, electronic equipment and a storage medium, in the embodiment of the invention, a callee register mechanism is introduced in the program code compiling process, so that when a program runs, if a called function needs to modify a register in a callee storage register set, the callee storage register set can be modified, and the program code compiling efficiency is improved. If the value of the register does not need to be modified, the value of the register is stored to the call stack and recovered to the register when the call is finished, and if the value of the register does not need to be modified, the value of the register can not be stored to the call stack, so that the instruction consumption can be reduced to a great extent, and the computing power resource consumed by storing the register is reduced; the register modification frequency is reduced, and the program code performance and size are improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a program code compilation method, apparatus, electronic device, and storage medium. Background technique [0002] The program code usually includes multiple functions, and the multiple functions have both a calling function and a called function called by the calling function. When the calling function calls the called function, it needs to pass data through registers and the call stack. Usually, when the calling function calls the called function, it is assumed that the called function will modify the values ​​stored in all registers in the CPU (central processing unit, central processing unit). On the call stack (Call stack), and after the function call ends, the value saved in the call stack is restored to the register. If the code size of the program code is relatively large and there are many called functions, the above method will waste a lot of computin...
